Subject: [GIT PULL] sysctl fixes for v5.19-rc7

Linus,

I've only received one fix for sysctls for v5.19-rc cycle. It's perhaps
silly to send a pull request for just one patch but oh well.

I'll take that time given I am sending a pull request to note that
Kuniyuki Iwashima has posted a trove of fixes with races for when a
subsystem does not do proper locking for read/write to the variables and
so has put effort to do this where applicable by ensuring the sysctl
proc stuff uses READ_ONCE/WRITE_ONCE helpers. Since most of the issues
there have been identified on networking side Dave has picked all that
up. I'll let him decide if he wants that on the rc or not.

I figured I'd mention I don't have much cleanups for kernel/sysctl.c queued up
for v5.20 so expect little work there later for the next cycle. That
should also help with deciding if Kuniyuki's fixes get merged on v5.19
or v5.20 as there shouldn't be any expected conflicts either way.

  Luis
